step-by-step directions

In a large bowl, beat together the Butter, Peanut Butter and Sugar until fluffy. Add the Vanilla Extract and Salt and stir to combine. Stir in the Flour, making sure not to overwork the dough.

Turn out onto a lightly floured surface and work dough together and shape into a disk. Wrap tightly in plastic and chill for 30 minutes.

On a lightly floured surface, roll out dough to 1/4" thickness. Cut into 2" disks (or a size slightly smaller than the mold you are using.

Place the dough circles onto a parchment lined baking sheet and cook for 4-5 minutes or until cooked but not hard.

Remove from oven and allow to cool completely.

For Chocolate Mousse:

Combine the Espresso and Almond Liquor in a small bowl and sprinkle Gelatin over top. Allow to bloom for 5-7 minutes.

In a double boiler, melt the Chocolate and the Butter. Mix in the Egg Yolks and Gelatin mixture. Cover, and set aside.

In a stand mixer or using a hand mixer, whip the Egg Whites and Cream of Tartar until foamy, then gradually add two tablespoons of Sugar and continue to whip until stiff peaks form. The Whites should glossy and not dry. Set aside.

In another bowl, whip the Heavy Cream, remaining Sugar and Vanilla Extract until soft peaks form.

Mix a few spoonfuls of the Egg White mixture into the Chocolate Mixture, and then gently fold the Egg Whites into the Chocolate Mixture until thoroughly combined. Fold in Whipped Cream. Transfer to a piping bag.

Pipe the mousse into mini half sphere silicon molds so they are 2/3 way full. Place a Shortbread cookie on top of each mold and freeze for 2 hours.

Place a baking rack on a parchment or wax paper covered sheet pan. Put frozen bombes on rack. Pour Chocolate evenly over bombes. Reuse Chocolate dripped on sheet pan if need be. Place in the freezer to set Chocolate, about 5 minutes.
